ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

"Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

My email messaging seems to be set at a defined format with double spacing. I prefer to use single spacing but in order to do this I have to type all the way to the end of the page and then it will automatically go to the next paragraph and will then use single spacing. I would really like to be able to format my emails with single spacing and different margins other than what I have to use now (i.e.using the entire width of the message). I cannot find any way to change this automatic double spacing and change the width of the paragraph at the same time. From the drop down list directly above the body of the message, I have tried changing from Body Text to Paragraph and back again, but nothing works. Thanks very much for your help.

P. S. I am using Windows 10 with Thunderbird version 128.4.2 esr. I had the same problem in more recent versions but not in older versions.

When i right click then i see a huge list of options i never had before, and open in next tab, copy and paste are no longer working. Added a screenshot of half the list of options i see when right clicking. It includes copy and mut and full screen options for video that i never had before.

135.0.1 (64-bit) on Win11

The security sequence for log-in is supply of user-id and then password; that works fine; then a send unique code dialogue pops up and it leads to an error screen which I am attaching. I have rung the number provided and they say they don't support Firefox; so that looks like end of Firefox use to me and goodbye (can't find a tearful emoji to insert).

Gotta say this kind of thing is happening quite frequently for me; mostly without a nice error screen like this one; last one I recall was hunting for car insurance; on the screen where it listed the billions of quotes to eager providers none of the links to click through for the quotes worked... and with this happeneing more frequently now you go... ohh it's firefox again isn't it... so you reluctantly fire up Google Chrome and of course it works OK.

So I'm kinda here with a broader outlook than just this specific problem; I really am on the verge of giving up with Firefox; it should just work shouldn't it; and it increasingly doesn't anymore; I don't want to get into an extended and convoluted dialogue to help you cure this issue; I'm simply perplexed that some really basic stuff doesn't work anymore; however; I've used Firefox for centuries so thought I should give you at least a chance so I could declare how I feel etc.

I am up for a dialogue over this and hoping this is an easy fix; but; as I say; I'm confused as to why, for me, Firefox just simply doesn't work well anymore; it just should and I shouldn't be here.

I tried gleaning this single outgoing email of "excessive spam/sales language" (I am only thanking someone for their purchase, not asking for another); "excessive links" (they and their graphics were fine before). no "excessive emailings/quantities" (I am only sending one single email and don't do more than a few with this content ever and haven't send even one email like it in weeks); co0ntacted my internet provider (RCN Astound can't help me and told me to contact Thunderbird), I already checked POP & SMTP stuff...

"Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-101] Message blocked due to spam content in the message.. Please check the message and try again."

What do I do?

I even checked that I had the latest version of Mozilla Thunderbird: yep! :/

Postbox having been sold to eM Client, I need to migrate to Thunderbird. Import worked pretty well using the protocol "migrating from a previous Thunderbird installation" however the filters did not import at all. It happens that I have 320 of them, so it would be a great help if some automatic procedure could be implemented. Is this possible? Thanks in advance. Regards, Gérald

I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

• DNS over HTTPS turned off
• Uninstall all add-ons
• Reinstall Firefox
• Create new profile and set it as default
• Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

My Ubuntu computer's network interface has failed. I need to address that. Before doing so, possibly with an OS re-install, I need to export my (thunderbird) email.

Since my configuration is 2.9GB (i.e, > 2GB), I can't use the zip file. So I have rsync'd the email profile to a USB stick.

I want to import this into a clean new thunderbird location on another Ubuntu machine. I can find no way for Tb to import the copied files. Going through the documented procedure, Import Tool -> Import from another Tb installation -> Choose a profile folder -> "Import failed unexpectedly, more information may be available in the Error Console."

Where is the Error Console? I must be doing something simple and wrong. What is it? Or should I give up on Tb completely?

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

I have been looking all over Firefox for the setting to change the icon (was included in the latest update notes) but it’s nowhere to be found for me. Am I missing something?

Hello. I would like tell about a problem. Before the icon was black, but now it is WHITE. it’s so ugly! I wanna change it to black color. how I can do it? I don’t want to do it through “shortcuts” because it sands me notifications. I hope that you will add this possibility or already it is possible. заранее спасибо!

I'm using thunderbird for gmail account, and I struggle to mark some events notification as completed when they are deleted using gmail interface. They keep on poping up but when I hit `Dismiss` it gives me this error: ``` Status Code: 2147500037, The request cannot be processed.

Server Replied with 400 If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view. ```

I don't want to make my calendar read-only because I'm still gonna use it but I can't remove these annoying pop-ups because of the error. Please help what can I do

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

Due to relevant policy and legal reasons, the Chinese version of Firefox has been used https://accounts.firefox.com.cn/ As a login account URL, it is also used in the international version https://accounts.firefox.com As login URLs, the two accounts are not interconnected. After recently upgrading to a new computer and downloading Firefox again, I am unable to use the synchronization function https://accounts.firefox.com.cn/ Login to the account, the specific manifestation is to enter the correct password when logging in, and it will continue to display 'processing'. But by directly entering the above website address, you can log in to your account normally. I now need a solution to the synchronization issue by moving bookmarks, plugins, themes, and synchronized tabs from my previous Firefox computer to my new computer.

由于相关政策法方面原因，中国版的firefox使用了https://accounts.firefox.com.cn/作为登陆账户网址，同时而国际版使用https://accounts.firefox.com作为登陆网址，两者账户不互通。

最近换了新的电脑以后，重新下载firefox，使用同步功能时，无法使用https://accounts.firefox.com.cn/登陆账户，具体表现是登陆时输入正确密码后登陆，一直显示处理中。但是直接输入上述网址，可以正常登陆账户。

我现在需要可以解决同步问题的方法，将我原来电脑中firefox中的书签，插件，主题以及同步的标签页移动到新电脑中。

Hi!

I've noticed dropped frames in videos for a while now, but only recently tested the issue. Using youtubes stats for nerds, I found that when videos have a small viewport resolution, it starts to drop frames. (I would test with other sites but only know of youtubes stats for nerds system to detect issues like this) For example a viewport resolution of 1250x703 does not drop frames, however by unmaximising the screen and the viewport resolution drops to 681x383, it begins dropping frames.

Using my 2nd monitor which has a smaller actual resolution, the video drops frames unless fullscreened, see recordings below. Test A | Firefox Maximised but video not fullscreen Test B | Firefox Maximised and video fullscreen This issue also occurs with picture-in-picture mode.

Disabling hardware acceleration fixes this issue but for some reason only affects firefox, using MS Edge with "graphics acceleration" enabled does not result in this issue. Is this potentially an issue specifically with how firefox handles hardware acceleration? Also since I require hardware acceleration to be enabled for 3D model work in my browser, is there something I'm missing here that would allow me to keep hardware acceleration on but not have this issue?

Any help is much appreciated, thanks!

I don't know whether this happened after an update - there was one a few days ago, but I only realised this morning, after switching on the computer, that all my bookmarks are missing. The toolbar is there, empty, only reading "For quick access, place your bookmarks here on the bookmarks toolbar"... I wish! I tried to restore the bookmarks - but it seems there is no backup to restore at all. Then I tried to check my profiles, but there is only the one currently in use. Then I tried to move a tab to the bookmarks toolbar - and nothing happened. Then I began to panic: toolbar apart, we're speaking about years of bookmarks, most of them related to my research for my books... All the advice in the support seems to point towards profiles and backups, but, as I said, it's clearly not my case... Please, please, please: help!

Greetings! I downloaded Thunderbird for my new Win11 desktop, but it gave me an ESR version 128.9.1. It's working fine, but can i just move to the current 137.0.1 version? If so, how do I do that - just grab the current version and install on top of the ESR or should I remove the ESR first? Thanks in advance!
